Hi, i have a question about centralized licensing.
We have bulding 1 with one controller and building 2 with other controller, lan-to-lan link between those buildings. Both building have their own intternet link.
Licenses are installed only in controller in building 1 for the total number of APs in both buildings, so we need to use centralized licensing.
At this moment, APs in building 2 are registered in controller in building 1 (because ccontroller in building 2 is in standby mode), so there are many traffic in LAN-to-LAN link.
We want to explore an architecture where centralized licensing is maintained, but controller can work in active-active mode, so APs in building 1 registrer with controller 1, and APs in building 2 register in controller 2. Additionally, is desired that controllers should be backup for each other, if controller 1 fails, all APs in building 1 register in controller 2, and viceversa.
Is this architecture posible in Aruba?? i have experience with other manufaccturers and it is posible but Aruba documentation is a little confusing about that escenario.

You make the controller in building 1 a master and the controller in building 2 a local controller. If you turn on centralized licensing, they will automatically pool and share licenses. You can make the APs in controller 1 find controller 1 by using DHCP option 43 and 60 to point those access points to controller 1. You can do the same with controller 2. http://www.arubanetworks.com/techdocs/ArubaOS_64x_WebHelp/Web_Help_Index.htm#ArubaFrameStyles/DHCP_Option_43/Windows_Based_DHCP_Serve.htm#dhcp_option_43_3357486196_1050520
